From what I understand there is difference between US and EU rules. In the EU the safety rules are legislation, but in the US they are rules by the insurers (UL). I guess the latter makes it harder to stop their import. Am I right?
Not quite. The U.S. does not have a federal standard. We have the National Electrical Code which is adopted as law/legistlation in all 50 states, with minor modifications here and there.

One good example is that San Francisco allows you to have knob and tube wiring in insulation, etc. If you remodel or rebuild, you have to build it “up to code”.
UL is not an insurer. It is a certified body, just like CSA, Intertek, or German TÜV SÜD. UL is a global non profit. It provides third party independent evaluation instead of self certification.
